<p class="MsoNormal">Another nice quality of Paraloid B-72 is that you can mix it yourself from dry granules (we use acetone, though other solvents work too) so you can make a thin solution to act as a penetrating primer, then a thicker one to be the actual
adhesive between the primed surfaces. If you have a clean break in something like bone, however, you can use a very thin solution as the adhesive and get an almost undetectable bond layer.
<o:p></o:p></p>
<p class="MsoNormal">I agree that PVA is not good for museum specimen work; apart from anything else, the A stands for Acetate, and it gives off acetic acid as it cures. It’s great for bonding wood, though.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">I fully agree with Mariana’s recommendation of Paraloid B-72. As she notes cyanoacrylates and epoxies are too strong, with a tendency to discolor. Epoxies are difficult to reverse and remove. PVA’s (like white
glue) are designed for paper and wood and will expand and contract with fluctuations in relative humidity. They have what is called cold flow, which means that they will shift as the environment changes.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">I am available to chat as well. But Mariana’s advice to find a local conservator who can advise you on local options is excellent.

<p class="MsoNormal" style="margin-left:.5in">I would recommend the use of a museum-grade (also referred to as archival quality) adhesive for any museum related purposes. For this reason, Paraloid B72 is an excellent choice. There are others out there and we
can continue to chat if you wish, but my other recommendation would be to speak to a local conservator who can guide you to find the best one(s) in your area.<o:p></o:p></p>
